> As described in the Nabble thread, "custom selector / filter for messages", I have implemented
message call support in selectors, together with a few initial functions and the ability to
register new functions without modifying the core.
> Attached is a patch that implements this feature.
> There are no unit tests currently implemented, but I can provide them in the near future
if needed.
